[Trilinos-Users] Kronecker product in Trilinos using parallel processes

Hi,

I am trying to generate a really big matrix that I obtained by summing
Kronecker products of square matrices of different order, some thing like
this:

SUM_{i=1} to {i=N} I(i-1) ⊗ A ⊗ I(N-i)

where  A is a square matrix of size 3 and I(i) is identity matrix of size
3^i. Since this is a repeated operation with varying sizes for i, is there
efficient way to handle this kronecker product in Trilinos using MPI?

Thanks,

Solomon
